<3 Sweet sixteen ideas? <3?

my party will be in October. I want to have anywhere from 20-100 people at my party. I still need a theme for my party too. I was going to rent a club for my party but i thought people might get tired of dancing and then there would be nothing to do and people would get bored. This will be the last party i get to have so i want it to be awesome!!! :D any ideas???
